  • 1.5-2.5hrs access,
  • 3-4hrs descent
  • 10min exit 

With a huge catchment, tricky access and high commitment, this canyon has only been descended a few times.  Some have called it “Wilson Creek on Steroids” for its high flows, narrow canyon and dangerous features.

A viable route only in very low flow conditions in late summer:  even very experienced teams have had some close calls in here with siphons in ‘normal February flows’.  This is a canyon to take very seriously, but all who have been were very impressed at the beauty and power of the canyon.

First descent: Dave Vass and Scott Hall, 19 March 2010.

Thank you to Alain Rohr, Jethro Robinson, Justin Wimmer and Erwan Coq for updated information on this canyon.

These were taken on the first descent, showing extremely low water levels

Taken from a descent with Justin Wimmer in April 2022. After a long dry summer, but you can still see the water level is higher than on the first descent… (Compare the final pitch images from the two galleries…)

    Didymo in fish, a few anchors replaced, maybe only 2 stars, would probably be 3 stars if there was higher flow, not as good as wilsons

    We (Team of 2) did first Powder Flask (2,5h) and than Fish River (3h). The Hike in took us 3 hours and was not to bad of a bush bash. The Powder Flask was low flow and Fish River was in Normal flow. We didn’t found any new big hazards in Fish. We replaced a few webbings in Powder Flask and Fish River.

    R3 in Powder Flask is now 15m, an extra bolt that we placed makes R4 (28m). R3 still could be done in one go. But it is harder to retrieve the rope.

    We did the canyons after a long periode of no rain and in the end of feb ( so no more melting water from the snow)

    • Date: 16-3-2022
    • Water level: normal
    • Anchor conditions: we did some repairs
    • Group size: 2
